The RoyPow Golf Cart Lithium Battery is a safe and reliable power solution designed for golf carts, offering a drop-in replacement for traditional lead-acid batteries. It integrates an advanced cell management system to ensure optimal performance and longevity.
Function Description
The primary function of the RoyPow Golf Cart Lithium Battery is to provide power for golf carts. It is designed as a direct replacement for lead-acid batteries, simplifying the upgrade process. The integrated cell management system (BMS) continuously monitors and manages various aspects of the battery's operation, including:
- Cell Balancing: Ensures all individual cells within the battery pack maintain similar voltage levels, which is crucial for maximizing battery life and performance.
- Battery Voltage Monitoring: Tracks the overall voltage of the battery pack to prevent over-discharge or over-charge conditions.
- Battery Current Monitoring: Monitors the current flowing in and out of the battery, protecting against over-current situations.
- Pre-warning for Low Capacity: Provides an alert when the battery capacity drops below 20% via RS485 communication, prompting the user to recharge.
- Battery Temperature Monitoring: An integrated temperature sensor monitors the battery's internal temperature, preventing operation outside safe temperature ranges.
The battery features a "MAIN SWITCH" button for turning the unit on and off. A green light indicates that the battery is powered on. For monitoring remaining capacity, an external battery meter connects via an RS485 connector. This meter displays capacity using ten bars, with each bar representing 10% of the total power. The system also includes an alarm function that sounds when the battery reaches low voltage levels (two bars remaining, then one bar remaining), signaling the need for immediate recharging.

Usage Features
The RoyPow battery is designed for user-friendliness and safety:
- Drop-in Replacement: Engineered to directly replace existing lead-acid batteries in golf carts, simplifying installation.
- Easy Installation: The manual provides clear steps for battery replacement, including disconnecting old batteries, installing mounting brackets (if necessary, as different models require different brackets), and connecting the new battery.
- Simple Operation: A single "MAIN SWITCH" button controls power, with a green light indicating operation.
- External Battery Meter: An included battery meter connects via an RS485 cable to display remaining capacity, offering a visual representation of power levels.
- Low Voltage Alarm: The battery meter provides audible alarms at 20% and 10% capacity, prompting timely recharging to prevent sudden power loss.
- Safety Protections: The integrated BMS protects against over-temperature, over-current, under-voltage, and external short-circuits, enhancing operational safety.
- Dedicated Charger: The battery must be used with a designated charger provided by RoyPow to ensure proper charging and prevent damage.
Maintenance Features
Proper maintenance ensures the longevity and performance of the RoyPow battery:
- Storage Guidelines: For storage exceeding one month, the battery should be placed in a dry, ventilated room with a temperature between 32°F~95°F (0°C~35°C). It should be stored away from corrosive materials, fire, and heat sources.
- Preventing Over-Discharge: For long-term storage, the battery's power must be turned off, and the State of Charge (SOC) should be kept above 60%. The battery should be fully charged and then recharged every 8 months to prevent over-discharge.
- Authorized Personnel Only: Only authorized personnel are permitted to operate or make adjustments to the battery, ensuring safety and proper handling.
- Damage Prevention: Users are warned against disassembling, resembling, or repairing the battery, short-circuiting it, exposing it to water or heat, inserting objects, striking it, or welding on it.
- Handling Damaged Batteries: If the battery is damaged, users should contact the place of purchase and cease use if it is waterlogged, distorted, or broken.
- Environmental Considerations: The battery should not be operated in explosive atmospheres or near flammable materials. It must not be allowed to freeze, and a frozen battery should never be charged.
- Disposal: As the product contains lithium-ion batteries, it must be disposed of properly according to local laws and regulations when worn out.
- Warranty: The battery comes with a FIVE-year limited warranty from the date of purchase against defective material or workmanship. This warranty is non-transferable and requires proof of purchase. It covers repairs or replacements at RoyPow's discretion for defects within the warranty period, provided the product was used according to the manual and not subjected to misuse, unauthorized repairs, or extended storage without recharging.
